Choices are: * Respin the board to move the via so that it is no longer under the pad. * Have the board fabricator plug and plate over the via. Search the fine SMTnet Archives for background.

Are these shorts occuring after reflow, or are they shorted on the incoming boards before stuffing? If the latter, is the fabricator doing electrical test? How are these boards getting past their electrical test? Especially if multilayer, there's

"Thats why i love this site its good for information and offers updated information to everyone" As long as the information isn't a fabrication, I would agree with you. Folungwin has installed no more than 5 printers in the US........and likely the

Well something is different isn't it? * Paste * Part supplier * Board fabrication * Was the profile that you reference the measured temperature or the the settings keyed into the oven? The cross sections seem to show less than expected ball collapse

Q1: You say that 0.008" of "slop" is un-doable; hence, the reasons for our failures. Any basis for that statement? A1: We're not even considering the accuracy of your placement machine. We base our comments on the gap between the hole and the connec

Each thermal cycle decreases the thickness of the OSP. So depending on the material, fabrication method, and blablabla; after one thermal cycle we'd expect the OSP to provide adequate protection for a couple of days. After that, you may need a more a

One other note, NEVER have an ENIG board fabricated by a house that "farms out" the gold. This always ends in disaster! Make sure whoever you choose does the whole process.

So, this fine designer thinks the cost of you putzing around with is thing is cheaper to the comapny? No. The fine designer is measured on in-bound cost, but not on the impact on overhead of those in-bound costs. OK, try this one: Have your fabric
